请教压缩和解压缩算法 LZMA.dll 测试程序

我现在想使用 LZMA 压缩算法中的 LZMA.dll ,但总是调试不出来 LzmaCompress zmaUncompress 这两个函数不知参数如何给。请大家帮忙看看
这是压缩部分 我感觉可能主要是参数问题

	HINSTANCE hInst;

	hInst = LoadLibrary("LZMA.dll");

	

	typedef int (_stdcall *FuncCompress)(unsigned char *dest, 

										 size_t *destLen, 

										 const unsigned char *src, 

										 size_t srcLen,

										 unsigned char *outProps, 

										 size_t *outPropsSize, /* *outPropsSize must be = 5 */

										 int level,      /* 0 <= level <= 9, default = 5 */

										 unsigned dictSize,  /* default = (1 << 24) */

										 int lc,        /* 0 <= lc <= 8, default = 3  */

										 int lp,        /* 0 <= lp <= 4, default = 0  */

										 int pb,        /* 0 <= pb <= 4, default = 2  */

										 int fb,        /* 5 <= fb <= 273, default = 32 */

										 int numThreads /* 1 or 2, default = 2 */

  );



	FuncCompress    MyCompress = (FuncCompress)GetProcAddress(hInst, "LzmaCompress");

 

	if(!MyCompress)

	{

		MessageBox("获取compress函数地址失败! ");

		return;

	}	

 

	unsigned int  dlen = sizeof(m_ucdecompress); //m_ucdecompress 压缩后的数据存储区

	size_t *destLen = &dlen;					//认为压缩后的数据长度



	const unsigned char srcarr[] = "12ac56";//hello hello hello world hello hello hello world

	const unsigned char *src = srcarr;

	size_t srcLen = sizeof(srcarr);

	m_unCompressLen = srcLen;					//要压缩的数据长度,在解压时做为解压后的数据长度

	



    unsigned char outpprops[1024];	           //这个参数不知什么作用，不知给什么值合适

	unsigned char *outProps = outpprops; 



	unsigned int   PropsSize = 5;             //这个参数也不知什么作用，其值要求必须是 5

	size_t *outPropsSize = &PropsSize;		// outPropsSize must be = 5    

	

	int level = 5;								// 0 <= level <= 9, default = 5

	unsigned dictSize = 1 << 24;				// default = (1 << 24)  16777216  1000000000000000000000000

	int lc = 3;									// 0 <= lc <= 8, default = 3

	int lp = 0;									// 0 <= lp <= 4, default = 0

	int pb = 2;									// 0 <= pb <= 4, default = 2

	int fb = 32;								// 5 <= fb <= 273, default = 32

	int numThreads = 2;							// 1 or 2, default = 2





    int status = MyCompress(m_ucdecompress, 

							destLen, 

							src, 

						    srcLen,

						    outProps, 

						    outPropsSize, 

						    level, 

						    dictSize, 

						    lc, 

						    lp, 

						    pb, 

						    fb, 

						    numThreads  );



//解压部分不能解压正确  下面是解压部分



	HINSTANCE hInst;

	hInst = LoadLibrary("LZMA.dll");



	typedef int  (_stdcall *FuncUnCompress)(unsigned char *dest, 

											size_t *destLen, 

											const unsigned char *src,

											size_t  *srcLen,

											const unsigned char *props, 

											size_t propsSize

											);



	FuncUnCompress  MyUnCompress = (FuncUnCompress)GetProcAddress(hInst, "LzmaUncompress");



	if(!MyUnCompress)

	{

		MessageBox("获取uncompress函数地址失败! ");

		return;

	}



    

	unsigned char destarr[1024];

	unsigned int  dlen = m_unCompressLen; //  解压缩后的数据长度 即原文长度

	unsigned char *dest = destarr;  

	size_t *destLen = &dlen;	 



	size_t  usrcLen = m_unDeCompressLen;  //要解压数据长度

	size_t  *srcLen = &usrcLen;



 

	const unsigned char outProps[12] = "12345678910";	//这个参数不知何用 也不知给值多少

	size_t   outPropsSize = 5;		// outPropsSize must be = 5    



	int status = MyUnCompress(dest, 

							  destLen, 

							  m_ucdecompress,       //解压数据

							  srcLen,

							  outProps, 

							  outPropsSize

							  );
